Peach tree named &#34;FLATHEART&#34;

ABSTRACT

A new and distinct variety of white flat peach tree denominated ‘FLATHEART’ which have fruits with large size, high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet cream white flesh which becomes pink at maturity time, and has a red pigmentation into and around the stone cavity, and an attractive skin with a high percentage of luminous purple red blush on skin surface, on a red to light red background.

This application claims priority of Community plant variety right No. 2020/3069 filed on Nov. 30, 2020 (Nov. 30, 2020) which is hereby incorporated by reference in its entirety.

Botanical classification: Prunus persica (L.) Batsch.

Variety denomination: ‘FLATHEART’.

The new variety named ‘FLATHEART’ is also known as 8C.10.141.14 PBPL or ASF1492. Indeed, before giving a name to a new and distinct variety of fruit tree, a provisional reference is assigned, considering the references of a tree in orchard. This provisional reference is constituted firstly with the number of the parcel on which the tree has grown, then the number of the line, the tree number and finally the year of selection. Then before being named ‘FLATHEART’, the provisional reference of this white flat peach tree variety was 8C.10.141.14, corresponding to the tree 141 located in line 10 of the parcel 8C and selected during the year 2014. The letters “PBPL” are related to the first letters of the type of tree in French (PBPL for “Pêche Blanche PLate”, that means “white flat peach”). Once the hybrid selected, the breeder assigned a clone reference that begins with the letters “ASF” followed by the year of selection and a number corresponding to the maturity order. The final name is only assigned once the application has been filed and the name approved after its publication in the official bulletin. For the variety ‘FLATHEART’, the clone reference was ‘ASF1492’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white flat peach tree, Prunus persica (L.) Batsch, which has been given the variety denomination ‘FLATHEART’.

This new tree produces fruits with a long shelf life without alteration both on the tree after growth completion and after harvesting, very good eating quality, semi-clingstone cream to slightly pink (at maturity time) flesh fruits, generally with a red pigmentation around and into the stone cavity, for fresh market in August in the Pyrénées-Orientales department, France.

ORIGIN OF THE VARIETY

The ‘FLATHEART’ white flat peach tree originated from a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested.

This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontane’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘FLATHEART’ variety results from pollinated cross between the white nectarine variety named ‘NECTARRELIE’ (not patented) which was used as the seed parent, or female parent, and the white flat peach variety named ‘FLATREINE’ also known as ‘ASFPBF0796’ (U.S. Plant Pat. No. 22,495) which was used as the pollen parent, or male parent.

The ‘FLATHEART’ variety was obtained by hybridizing and propagated by grafting on a ‘INRA® GF677’ (non-patented) rootstock trees. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of the standard rootstock trees set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées-Orientales, France. More particularly, the plant was reproduced by grafting.

SUMMARY OF THE VARIETY

The new and distinct variety ‘FLATHEART’ white flat peach tree blooms at the end of February or early in March near Elne in the Pyrénées-Orientales department, France. The blooming period is considered medium. However, it was observed that its date of blooming seems to be highly dependent on climatic conditions.

The first fruit of ‘FLATHEART’ ripens generally medium in the season, namely during July or early in August. However, it was observed that its date of maturity seems to be highly dependent on climatic conditions.

DETAILED BOTANICAL DESCRIPTION

The trees, flowers, and fruits may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruits by ‘FLATHEART’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are medium vigorous and large stature half-standing in an upright out aspect. The anthocyanic coloration of flowering shoot is present excluding brushwood side away from sun. The time of beginning of flowering is considered medium; flowering begins at the end of February or early in March. The type of flower is showy (rosette) with small petal size. Petals are pink. Leaf glands are present and reniform. The fruit flesh is cream and the flesh color evolves to become slightly pink at complete maturity. The fruit flesh usually shows a red pigmentation into the stone cavity and radiating around the stone cavity on approximately 4.0 to 5.0 millimeters. The fruit skin is medium thick, with a luminous purple red blush on a red to light red background. The stone is semi-clingstone and its size is small to medium. Fruit taste is semi-sweet, very aromatic and with a high level of sugars.

Compared to ‘FLATBOOM’ white flat peach variety (U.S. Plant Pat. No. 33,511), the fruits of ‘FLATHEART’ usually ripen later in the season. However, the fruits of the new variety ‘FLATHEART’ show a more regular shape than those of the ‘FLATBOOM’ variety. The fruit skin of the new variety ‘FLATHEART’ is pink purple red cream more luminous than the color of the fruit skin of the similar variety ‘FLATBOOM’. The fruits of the new variety ‘FLATHEART’ show a white to cream flesh, with a slightly red pigmentation, which becomes pink at complete maturity, whereas the fruit flesh of ‘FLATBOOM’ is white.

Compared to its seed or female parent, i.e. the ‘NECTARRELIE’ variety (not patented), which is a white nectarine tree, the new variety ‘FLATHEART’ is a white flat peach tree. The new variety ‘FLATHEART’ and its female parent ‘NECTARRELIE’ have a similar blooming period. However, the fruits of the new variety ripen approximately 25 days later than the fruits of the variety ‘NECTARRELIE’.

Compared to its pollen or male parent, i.e. the ‘FLATREINE’ variety also known as ‘ASFPBF0796’ (U.S. Plant Pat. No. 22,495) variety, the new variety has a similar blooming period and a similar ripening period. However, the new variety ‘FLATHEART’ will be preferred as ‘FLATREINE’ because of its fruits showing a bigger size than the fruits produced by ‘FLATREINE’. The productivity of the new variety is also more important than the productivity of ‘FLATREINE’.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white flat peach tree, the following was observed on trees in their fifth growing season (four year of production) under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales department, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘INRA® GF677’ (non-patented) trees. All major color code designations are by reference to The R.H.S. Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree:     -   -   Size.—         -   Generally.—Considered large. The tree size the first year             was approximately 200 to 280 cm. The tree was pruned during             each following dormant season to a height of approximately             250 cm. Current season shoots growth could reach 80 cm. The             tree size from the second year (second and next years)             reached a final height of 330 cm including current season             shoots length. The tree size is consistently reduced to 250             cm the next years.         -   Spread.—Approximately 100 cm with a cylindrical shape. The             whole orchard was oriented to a central leader organization,             with tree lines spaced of 4.0 meters and trees spaced of 1.0             meter in a same tree line. As a result, tree spread was             about 100 cm and the orchard contained 2500 trees by             hectare.         -   Vigor.—Considered medium.         -   Productivity.—Considered good to very good, and regular.             Fruit set is spaced by thinning to develop the remaining             fruit into the desired market sized fruit. The number of the             fruit set varies with the prevailing climatic conditions and             cultural practices employed during the bloom period and is             therefore not distinctive of the present variety. A reduce             vegetation, obtained with pruning or green pruning,             approximately 1 month or 1 month ½ before harvesting flat             fruits, significantly promotes fruit qualities, especially             growth, color and firmness. Moreover, contamination risks             due to monilia or rot are significantly reduced. ‘FLATHEART’             variety is not much sensitive to cracking of pistil cavity,             to cork formation into peduncle cavity or to monilia.         -   Bearer.—Very regular. The fruit distribution is considered             homogenous on mixed branches and spurs having more than 1             year. Thinning of 2 fruits out of 3 was necessary for the             tree valorisation. Thinning was necessary every year during             the years of observation.         -   Form.—The ‘FLATHEART’ variety has naturally upright shape.         -   Density.—Considered dense.         -   Hardiness.—The present tree was grown and evaluated in             France. The variety appears to be hardy in all stone fruit             growing areas of France and especially where the chilling             requirement is between 700 and 1200 hours. More             particularly, experimentations on the same orchard in Elne,             Pyrénées-Orientales department, with winter chilling             requirement below 7.2° C. comprised between 700 hours and             1200 hours according to the specificities of the year,             namely 1031 hours in 2012-2013, 777 hours in 2013-2014, 893             hours in 2014-2015, 718 hours in 2015-2016, 825 hours in             2016-2017, 1017 hours in 2017-2018, 844 hours in 2018-2019,             706 hours in 2019-2020 and 822 hours in 2020-2021 showed a             good behavior of the tree in all cases. No injury with             temperatures as low as −12° C. in winter. Good resistance to             late frosts. -   Trunk:     -   -   Diameter.—Approximately 56.0 to 60.0 millimeters in diameter             when measured at a distance of approximately 20.0             centimeters above the soil level for trees on second fifth             leaves (or fourth year of production)         -   Bark texture.—Considered rough, with lenticels.         -   Lenticels.—Numerous lenticels are present. The number of             lenticels reaches 2 lenticels per cm². The lenticels range             in size of approximately 4.0 to 4.5 millimeters in width,             and about 1.0 to 2.0 millimeters in height.         -   Lenticel color.—The lenticels show a light orange or beige             color (RHS Greyed Orange 164 D).         -   Bark coloration.—The bark has a brown to grey color (RHS             Grey 201 C) darker than the lenticels color. -   Branches:     -   -   Size.—The branches are pruned to approximately 1.0 meter in             length.         -   Diameter.—Average as compared to other peach varieties. The             current season shoots have a diameter of approximately 5.0             to 6.0 millimeters, and mature branches have a diameter of             approximately 7.0 to 8.0 millimeters.         -   Surface texture.—Rough, with lenticels, for current season             shoots and for mature branches, wood which is several years             old has no furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally 45 degrees from the             horizontal axis for current season shoots and 65° degrees             from the horizontal axis for mature branches. This             particular characteristic is not considered distinctive of             the variety, however.         -   Current season shoots.—         -   Internode length.—Generally 20.0 to 26.0 millimeters.         -   Color.—The color of new shoot tips is considered light green             (RHS Yellow Green 145 A) on lower part of new shoot tips,             whereas the upper part is darker and colored in purple (RHS             Greyed Purple 185 A), depending on the level on the tip and             the sunlight exposure.         -   Mature branches.—         -   Internode length.—Generally 20.0 to 24.0 millimeters.         -   Color of mature branches.—Brown (RHS Grey Brown N 199 B).         -   Lenticels.—Numerous lenticels are present on mature             branches. The number of lenticels reaches 4 lenticels per             cm². The size of lenticels is considered small on one year's             old shoots and medium on two-year-old shoots. The lenticels             range in size from approximately 1.5 millimeter in width,             and about 1.0 millimeters in height on one year's old             shoots. The diameter is between 1.0 and 1.5 millimeter on             two-year-old shoots.         -   Lenticel color.—The lenticels on mature branches have a             beige color (RHS Greyed Orange 164 B). -   Leaves:     -   -   Size.—Considered medium for the species. The ratio leaf             length/leaf width is 3.804.         -   Leaf length.—The medium length is about 174.60 millimeters             with leaf petiole.         -   Leaf width.—The medium width is 45.90 millimeters.         -   Leaf form (in cross section).—Concave.         -   Leaf form.—Lanceolate.         -   Leaf base shape.—Acute.         -   Leaf tip form.—Acute.         -   Leaf thickness.—Medium.         -   Leaf color.—         -   Upper leaf surface.—Green (RHS Yellow Green 147 A).         -   Lower surface.—A slightly lighter green (RHS Yellow Green             146 A or RHS Yellow Green 146 B) than the upper leaf surface             color.         -   Leaf texture.—Smooth and glabrous on both upper and lower             surfaces of the leaf.         -   Leaf venation.—Pinnately veined.         -   Mid-vein.—         -   Color.—Light green (RHS Yellow Green 145 A). The color may             evolve with maturity.         -   Width.—Approximately 1.5 millimeters.         -   Secondary veins.—         -   Color.—Light green (RHS Yellow Green 145 C).         -   Leaf margins.—Slightly undulating.         -   Form.—Considered crenate.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, one leaf of normal size is found with one or             two smaller leaves (at least 50% smaller).         -   Leaf petioles.—         -   Size.—Considered medium.         -   Length.—About 9.0 to about 12.0 millimeters.         -   Diameter.—About 1.5 to 2.0 millimeters.         -   Shape.—Grooved.         -   Petiole color.—         -   Upper petiole surface.—Green (RHS Yellow Green 144 B).         -   Lower surface.—A slightly lighter green (RHS Yellow Green             145 B) than the upper petiole surface color.         -   Leaf glands.—         -   Size.—Considered medium. Their length is about 1.0             millimeter and their width is about 1.0 millimeter.         -   Number.—Generally 2 glands per leaf.         -   Type.—Reniform.         -   Margins.—Smooth and regular.         -   Position.—Alternate on the upper part of petiole.         -   Color.—On young leaves, leaf glands color is considered a             light green (RHS Yellow Green 145 B). On older leaves, leaf             glands color turns to a brown (RHS Brown 200 A) color.         -   Leaf stipules.—         -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers:     -   -   Flower buds.—         -   Generally.—At pre-floral stage of development, the floral             buds are round shaped. Their form is evolving until             blooming, with variable dimensions. Just before blooming,             floral buds are approximately 8.0 to 10.0 millimeters wide             and approximately 12.0 to 18.0 millimeters long. The floral             buds show a homogenous distribution on the trees.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flower's buds, or calyx, or flower receptacle, is of             purple color (RHS Greyed Purple 187 A or RHS Greyed Purple             187 B) on its outer face. The inner face of the flower             receptacle is orange yellow (RHS Yellow Orange 23 A). The             corolla, formed by the petals, is generally of pink color             (RHS Red Purple 62 A or RHS Red Purple 62 B) on both faces.             Petals color shows an evolution until the end of flowering.         -   Hardiness.—The buds are considered hardy under typical             central Pyrénées-Orientales department climatic conditions.             No winter injury was noted during the last several years of             evaluation in the central Pyrénées-Orientales department,             with winter temperatures as low as −10 degrees Celsius in             January. The current variety has not been intentionally             subjected to drought or heat stress, but the variety showed             a very good resistance in orchard to temperatures up to 42             degrees Celsius with an average temperature between 28 and             30 degrees Celsius during 3 weeks in summer.         -   Date of bloom.—The blooming time generally begins at the end             of February or early in March. The first bloom was observed             on Mar. 1, 2018.         -   Blooming time.—Considered medium in relative comparison to             other commercial peach cultivars grown in the             Pyrénées-Orientales department, France. The date of full             bloom is observed generally at the middle of the blooming             period. The date of bloom varies slightly with climatic             conditions and cultural practices. Thus, the full bloom was             observed in 2018, from Mar. 1 until Mar. 8, then from Mar. 4             until Mar. 13, 2019, then from Feb. 25 until Mar. 2, 2020,             and then from Feb. 26 until Mar. 8, 2021.         -   Duration of bloom.—Medium, approximately between 7 to 11             days.

Furrows are deeper and more oblate on             lateral sides.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and at the             apical tip.         -   Ventral edge.—         -   Width.—Narrow. Approximately 2.0 millimeters at mid-suture.         -   Dorsal edge.—         -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is generally             considered light brown (RHS Greyed Orange 164 B or RHS             Greyed Orange 164 C).         -   Tendency to split.—Splitting is absent.         -   Kernel.—         -   Size.—The kernel is considered small.         -   Length.—Approximately 8.0 millimeters.         -   Width.—Approximately 7.0 millimeters.         -   Thickness.—Approximately 6.0 millimeters.         -   Form.—Considered round.         -   Pellicle.—The pellicle of the kernel has a smooth texture.         -   Color.—The kernel skin is brown colored (RHS Greyed Orange             N167 A). The almond, which is the seed of the kernel, is             white (RHS White 155 D) and has a sweet taste. The kernel             and its embryo are mature at the time of fruit maturity.         -   Use.—The subject variety ‘FLATHEART’ is considered to be a             white flat peach tree having a medium season of maturity,             and which produces fruits that are considered firm,             attractively colored in purple red. Fruits have semi-sweet             taste and are excellent for uncooked consumption, crunchy or             melting when at full maturity. Fruits have excellent             gustative qualities. Due to their flesh quality, firmness             and density, they can also be commercialized as 4th range             product (packed fruit or fruit in bags for example). And             they are also useful for both local and very long-distance             shipping.         -   Keeping quality.—Remarkable. Fruit have a slow maturation             and a long shelf life both on the tree after growth             completion and after harvesting without alteration. After             growth completion, fruits are preserved more than one week.             After harvest, fruits are well preserved more than 2 weeks             at 2.0 degree Celsius.         -   Shipping quality.—Considered very good. The fruit of the new             white flat peach variety showed minimal bruising of the             flesh or skin damage after being subjected to normal             harvesting and packing procedures. Its resistance to             handling during harvest and packing and its long shelf life             without alteration after harvest easily permit 2             weeks-shipping at 2 degrees Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety is not very             sensitive to Monilia or rot. The pistil cavity is completely             closed, generally without any cork formation. Although the             new variety of white flat peach tree possesses the described             characteristics when grown under the ecological conditions             prevailing near Elne, Pyrénées-Orientales department,             France, it should be understood that variations of the usual             magnitude and characteristics incident to changes in growing             conditions, fertilization, pruning, pest control and             horticultural management are to be expected. 

I claim:
 1. A new and distinct variety of white flat peach tree as illustrated and described, characterized by fruits with large size, high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet cream white flesh which becomes pink at maturity time, and has a red pigmentation into and around the stone cavity, and an attractive skin with a high percentage of luminous purple red blush on skin surface, on a red to light red background.
